Abstract

A diverse fauna of dendroid graptolites and graptoloids occurs in the Tremadocian Madaoyu Formation of the Panjiazui section, near Changde, Hunan Province, South China. The dendroids are Callograptus cylindricus, C. ellipsoideus, C. isolateralis, C. salteri, C. suxianensis, C. taitzehoensis, and Dendrograptus yini; the graptoloids are Anisograptus delicatulus, Anisograptus sp., Adelograptus sp., Staurograptus cf. mojotorensis, Rhabdinopora flabelliformis anglica, R. umbellata, Rhabdinopora sp. 1, and Rhabdinopora sp. 2. All taxa are figured and the selected graptoloid taxa are described. Based on this taxonomic revision, the Tremadocian Rhabdinopora flabelliformis anglica and Adelograptus biozones are recognized in the Panjiazui section, allowing correlation with other graptolitic successions worldwide.
